Platinum-Iridium AFM probe with the lowest spring constant
The 12PtIr400B is the updated version of RMN’s probe with the lowest spring constant, with prolonged mechanical wear. It is most useful for contact AFM measurements with minimum contact force. These probes are ideal for C-AFM, SCM, SMM and SMIM applications.The 12PtIr400A is the preferred probe for Keysight (Agilent) SMM applications.

Technical Features
Material: Solid platinum or platinum-iridium probe tip and cantilever supported on standard AFM probe sized ceramic chip, connected to conductive gold bonding pad with conductive epoxy. RMN also has probes available without gold contact pad, to help reduce stray capacitance.
Probes on standard sized substrates have a part number ending in the letter B (i.e. 25Pt300B).
Probes designed specifically for the Keysight (Agilent) Scanning Microwave Microscope (SMM) have the letter A rather than B (i.e. 12Pt400A).
Additional substrates:
- C - Substrate without gold bonding pad, to help reduce stray capacitance (= to A dimensions)
- D - Substrate has a 200um gold transmission line the entire length of the chip and the back is completely covered in gold (standard size chip)
- E - Substrate has the same features as the D substrate, only it is thinner (5 mil thick)
